EARL TOBIAS SCHMUCKER, 0F RAPID CITY, SOUTH DAKOTA.

MEANS FOR HANDLING GREAS COMPOUNDS.

Application filed J'une 2,

To all whom t may concern:

Be it known that I, EARLl ToBIAs SCHMUCKER, a citizen of the UnitedStates, and a. resident of Rapid City, in the county of Pennington and-State of South Dakota, have 1nvented` a new and useful Improvement inMeans for Handling Grease Compounds, ofV wh1ch the following is a full,clear, and exact description.

My invention relates to improvements in process and means for handlinggrease com' pounds and the like, and it consists in the stepshereinafter disclosed, and the combinations, constructions, andarrangements herein described and claimed.

An object of my invention is to provide a process for handling easecompounds which .will be able to eliver a predetermined quantity ofgrease.

A further object of my invention is to provide a process for handlinggrease comounds which makes use of means for deivering a desiredquantity of grease and for conveyin this quantity to the desired4 place.

A furt er object of my invention is tol provide a process for handlinggrease which greatly reduces the amount of handling which in usuallynecessary.

A further object of my invention is to provide a process which makes,use of a simple, efficient, and economical means for handling greasecompounds,`

A further objectL of my invention is 'to provide 'a novel grease gunwhich is ada ted to show the amount of grease contained within the gun.

A further object of my invention is to provide a novel means for fillingthe grease gun with the desired amount of grease.

Other objects and advantages will appear in the following specification,and the novel features of the invention will be particugrease retalmn'gdrum 1 which is preferably 1922. Serial No. 565,476.

made of metal and which has a centrally disposed outlet pipe 2 therein.The pipe 2 1s rigidly secured to the cover 3 of the drum at 4. An airIinlet 5 communicates with the top of the drum 1 and is adapted to beconnected to a pipe 6 conveying compressed air. The pipe 2 extendssubstantially to the bottom of the `drum 1 and has a manuallycontrolledvalve 7 disposed adjacent to the outer end thereof. The pipe 2 isfashioned into a socket 8 at its outer end and is adapted to receive thetapered end 9 of a grease gun. It is obvious from this construction thatwhen compressed air is admitted into the drum 1, it will force'thegrease 10 in the drum out through the socket 8 when the valve 7 isopened. If'desired,\compressed air may be left on all of the time.` Thegrease will be forced out through the socket 8 only when the valve 7 isopened.

`In Figure 2 I have shown the novel type ofv grease gun which isemployed with the drum 1.l As heretofore stated, this grease' gun has atapered mouth 9 which is carried by a pipe 11, this pipe communicatingwith the casin 12 of the gun. .A plunger 13 is slidably disposed in thecasing 12 and has a plunger rod 14 which projects through the end 15 ofthe casing 12 and extends into a cylindrical member 16 which is carriedby the casing 12. A disc 17 is secured to the rod 14 and snugly engageswith the wall ofthe cylindrical member 16. v The cylin` der 16 hasopenings 18 therein which are spaced from each other and are numbered l,2, 3, etc. A pin (not shown) is adapted to be disposed in any one of`the openings 18 and stops the movement of the rod 14 when the disc 17abuts the pin. In this manner, the numbers 1, 2, 3, etc., designate thequantity of greasev by weight which is contained within the casing 12.

From the foregoing description of. the various parts of the device, theoperation thereof may be readily understood. The drum 1 containinggrease may be filled at the grease manufacturing concern and be shippedto the desired destination. In filling the gun with the ydesired amountof grease, the end 9 is inserted into the socket 8 and the valves 7 and19'are opened` The resfsure` of the air upon the grease in the rum l1will force the grease through the pipe 2 and ,into the casing 12, the'ease moving the plunger 13 as it is forced lnto thel casing 12. Thedesired amount of grease has preof the viously been determined and thepin disposed in any one of the openings 18. The air pressure will forcethe lgrease into 'the casing 12 until the disc. 17 abuts the pin. Thevalves 7 and 19 may now be closed and the gun removed from the socket 8and be carried to any place desired. The casing 12 has a pipe 20communicating therewith to which a compressed air pipe may be attached.The gun may now be emptied of its contentsby merely attaching the airpipe to the pipe 20 and opening the valve 19, whereupon the plunger 13will be moved towards the tapered end 9 and' will force the grease outthrough the opening in the tapered end. The weight of the amount ofgrease delivered by the end 9 is known, since the pin was inserted inany one of the desired openings 18, these openings designating theweight of the amount of grease contained within the casing 12.

In Figure 3 I have shown a modified form of the device in which a pipe30 communicates with the drum l and has a plurality of branch pipes 31,these branch pipes being provided with valves and sockets 33.V

lVith this construction it will be observed that the drum V1 may bedisposed out ofsight, as for instance in the basement of a garage, andthe pipe 30 whichcommunicates therewith may be led to any part of thegarage and have as many valve controlled loutlet sockets 33 connectedtherewith as desired. It is obviousthat the grease within the drum 1will fill the pipe 30 and will be instantly discharged through thesockets 33 when they are opened. The grease gun. may be inserted in anyone of these sockets and be filled with the desired amount of grease inthe manner heretofore described.

In Figure 4 I have shown a modified form ease gun. `The modified form isidentica with the form shown in Figure 2 except in that a compressionspring 40 is disposed in the casing 12 and tends to move thev plunger 13toward the outlet pipe 11. The grease in being forced into the casing 12moves the plunger 13, which in turn compresses the spring 40. When theeasin 1 2 is filled with the desired amount o grease, the valve 19 isclosed and the grease within the casing 12 keeps the spring 40 Thisconstruction does away with the com-v pressed air in the pipe 20.

The device comprises a novel means for delivering a desired quantity ofstored grease to a grease gun; As heretofore stated, the drum 1 may bereplenished when empty, thereby providing a simple means of deliveringgrease from the manufacturer to the consumer. The grease gun whichcontains the desired amount of ease may be readily carried to any placeesiredand there be discharged of its contents. The graduated cylinder 16provides a simple and effective means for determining the quantity ofgrease contained within the casing 12. In this manner, any desiredamount ofdgrease may be Jforced into the casing 12 an from theredischarged into the working parts of the machine without the necessityof first weighing the amount of grease forced into the casing 12. Thedevice may be readily installed in any garage or a like greasedispensing station, and is efficient and durable for the purposeintended.

I claim:

i 1. A grease gun comprising-a grease containing casing havin an outletnozzle, said casing adapted to e filled with grease through said nozzle,a plunger slidably disposed within said casino' and having a stemprojecting through said casing, means for selectively engaging with saidstem to de-f termine the outward movement of said plunger, saidA plungeradapted to be moved by the grease entering the casing.

2. A grease gun comprising a grease conL taining casing havin an outletnozzle, said casing adapted to ie lled with grease through said nozzle,a plunger slidably disposed within said casing and having a stemprojecting through said casing, means for selectively engaging with saidstem t0 determine the' outward movement of said plunger, said plungeradapted to be moved by the grease entering'the casing, and a valve forclosing the inlet nozzle.
